Conceptualizing psychopathic traits from an evolutionary-based perspective: An empirical study in a community sample of boys and girls

Although psychopathy has historically been associated with a lack of emotion, recent research has suggested that psychopathy may represent a tendency to externalize the experience of unpleasant emotions, including shame, which could be seen as an adaptive strategy within an evolutionary framework. However, more empirical research is needed to build on this argument. This study tested a novel evolutionary-based model involving pathways associating the impact of harsh rearing experiences (warmth and safeness experiences and traumatic shameful experiences) with psychopathic traits as well as the indirect effects of external shame and shame coping strategies in this association. This study also tested the invariance of this model across gender. A youth community sample (N = 703; 58.9% girls) completed self-report questionnaires on the impact of harsh rearing experiences, external shame, shame coping strategies, and psychopathic traits. The results suggested that the impact of harsh rearing experiences was directly and indirectly (through external shame and shame coping strategies) associated with psychopathic traits. The model partially explained the endorsement of psychopathic traits in boys and girls, although gender differences were found in some of the pathways. These findings offer support for conceptualizing psychopathic traits as an adaptive strategy to cope with the impact of harsh rearing experiences, opening new perspectives for prevention and treatment.
